After you pull, you should see a new directory, /sys/src/9/teg2. From the _announce file:
This is a preliminary Plan 9 port to the Compulab Trimslice, containing a Tegra 2 SoC: a dual-core, (truly) dual-issue 1GHz Cortex-A9 v7a-architecture ARM system, *and* it comes in a case. VFP 3 floating-point hardware is present, but 5l doesn't yet generate those instructions. This is the first multiprocessor ARM port we've done, and much of the code should be reusable in future ports. There are still things to be done but it can run both processors and is believed to have adequate kernel support for VFP 3 floating-point.
